ABSTRACT
The problem of conserving our material resources is vastly different in regard to water from what it is in regard to the minerals. In the case of minerals it is primarily a question of abstention, of substituting wherever economically feasible some non-mineral material. But the water supply renews itself constantly; the rain which falls upon land, the snow which gathers in banks and glaciers, must sooner or later, whether in a day or in the course of hundreds of years, return to the ocean and be again available for evaporation and precipitation. The water supply, being perpetually renewed, should then be utilized fully; wherever possible it should be substituted for other materials…
To our savage predecessors obliged to descend a canyon and gather the trickling water in a jar, or make a long trip to a spring, how marvelous would it appear to see the present city dweller gather water anywhere by merely turning a faucet.
